Not a python programmer here and I'm only guessing after a cursory look recently. Twisted developers are layering a higher-level "architecture" over the basic system calls they have wrapped. It's just a few calls down there (serial and scatter-gather I/O, multiplexing, etc.) but twisted adds higher level data structures, and design-patterny conceptual models to shield the pythonista from Unix. Some of that gotta add some fat; which might be OK for the great majority of the people, but the few who need raw performance might end up cutting some bacon off. That dude at amix.dk actually knows his stuff.
